Swift springs are superior to the other brands in every aspect. If you want the competitive edge, you need Swift, period.

Swift made a name for itself on the tracks of Asia and Europe by defying all accepted concepts and speculations about the future, if any, in coil spring science. When everyone else was looking to expensive and brittle titanium composites to create the next evolution of springs, Swift was looking at reinventing the entire science of coil spring dynamics. Swift saw that most others are using the old silicone chrome material which was soft and heavy. It used a tempering method that damaged the strength of the material requiring more coils and, in turn, more weight. The material was also suffering from a short life-span. With springs like this leading the industry, Swift saw room for improvement.

Swift's R&D team created material, called H5S.TW, which was stronger than silicon chrome. It was so resilient that it required 2 rounds of shot peening in order to hold its coil shape and was so strong that it needed thinner wire compared to other manufactures. It also needed fewer coils, which greatly decreased weight while dramatically increasing available stroke.
